The TC s low dropout voltage, combined with the low current consumption of only 1.1 µa (typ), makes it ideal for battery operation. The low voltage differential (dropout voltage) extends the battery operating lifetime. It also permits high currents in small packages when operated with minimum V IN V OUT differentials. The circuit also incorporates short-circuit protection to ensure maximum reliability.

9 .0 PIN DESCRIPTIONS The descriptions of the pins are listed in Table -1. TABLE -1: PIN FUNCTION TABLE Pin No. Symbol Description 1 GND Ground Terminal 2 V OUT Regulated Output V IN Unregulated Supply Input.1 Ground Terminal (GND) Regulator ground. Tie GND to the negative side of the output and the negative side of the input capacitor. Only the LDO bias current (1 µa typical) flows out of this pin, there is no high current. The LDO output regulation is referenced to this pin. Minimize voltage drops between this pin and the minus side of the load..2 Regulated Output (V OUT ) Connect V OUT to the positive side of the load and the positive terminal of the output capacitor. The positive side of the output capacitor should be physically located as close to the LDO V OUT pin as is practical. The current flowing out of this pin is equal to the DC load current. 4.0 DETAILED DESCRIPTION The TC is a low quiescent current, precision, fixedoutput voltage LDO. Unlike bipolar regulators, the TC supply current does not increase proportionally with load current. 4.1 Output Capacitor A minimum of 1 µf output capacitor is required. The output capacitor should have an effective series resistance (esr) greater than 0.1Ω and less than Ω, plus a resonant frequency above 1 MHz. Larger output capacitors can be used to improve supply noise rejection and transient response. Care should be taken when increasing C OUT to ensure that the input impedance is not high enough to cause high input impedance oscillation. 4.2 Input Capacitor A 1 µf input capacitor is recommended for most applications when the input impedance is on the order of 10Ω. Larger input capacitance may be required for stability when operating off of a battery input, or if there is a large distance from the input source to the LDO. When large values of output capacitance are used, the input capacitance should be increased to prevent high source impedance oscillations.. Unregulated Supply Input (V IN ) Connect the input supply voltage and the positive side of the input capacitor to V IN. The input capacitor should be physically located as close as is practical to V IN. The current flow into this pin is equal to the DC load current, plus the LDO bias current (1 µa typical.) 200 Microchip Technology Inc. DS214F-page 9

10 .0 THERMAL CONSIDERATIONS.1 Power Dissipation The amount of power dissipated internal to the low dropout linear regulator is the sum of the power dissipation within the linear pass device (P-Channel MOS- FET) and the quiescent current required to bias the internal reference and error amplifier. The internal linear pass device power dissipation is calculated by multiplying the voltage across the linear device by the current through the device. EQUATION The internal power dissipation, as a result of the bias current for the LDO internal reference and error amplifier, is calculated by multiplying the ground or quiescent current by the input voltage. EQUATION P D (Pass Device) = (V IN V OUT ) x I OUT P D (Bias) = V IN x I GND The total internal power dissipation is the sum of P D (Pass Device) and P D (Bias). EQUATION P TOTAL = P D (Pass Device) + P D (Bias) For the TC, the internal quiescent bias current is so low (1 µa typical) that the P D (Bias) term of the power dissipation equation can be ignored. The maximum power dissipation can be estimated by using the maximum input voltage and the minimum output voltage to obtain a maximum voltage differential between input and output. The next step would be to multiply the maximum voltage differential by the maximum output current. EQUATION P D = (V INMAX V OUTMIN ) x I OUTMAX Given: V IN =.V to 4.1V V OUT =.0 V ± 2% I OUT = 1 ma to 100 ma T AMAX = C P MAX = (4.1V (.0V x 0.98)) x 100 ma P MAX = milliwatts To determine the junction temperature of the device, the thermal resistance from junction-to-ambient must be known. The -pin SOT-2 thermal resistance from junction-to-air (R θja ) is estimated to be approximately 9 C/W. The SOT-89 R θja is estimated to be approximately 110 C/W when mounted on 1 square inch of copper. The TO-92 R θja is estimated to be 11.9 C/W. The R θja will vary with physical layout, airflow and other application-specific conditions. The device junction temperature is determined by calculating the junction temperature rise above ambient, then adding the rise to the ambient temperature. EQUATION Junction Temperature SOT-2 Example: T J = P DMAX x R θja + T A T J = milliwatts x 9 C/W + C T J = 96.6 C SOT-89 Example: T J = milliwatts x 110 C/W + C T J = 67.8 C TO-92 Example: T J = milliwatts x 11.9 C/W + C T J = 70.
