1 General Description The series are positive voltage regulator ICs fabricated by CMOS process. Each of these ICs consists of a voltage reference, an error amplifier, a resistor network for setting output voltage, a current limit circuit for current protection and a chip-enable circuit (5-pin products only). The series feature high supply voltage ripple rejection, low dropout voltage, low noise, high output voltage accuracy, and low current consumption which make them ideal for use in various battery-powered devices. The series have 1.2, 1.3, 1.5, 1.8, 2.5, 2.8, 2.85, 3.0, 3.2 and 3.3 versions. The are available in standard SOT-23-3, SOT and CSP-4 packages. Features Low Dropout oltage at I OUT =100mA: 150m Typical (Except 1.2, 1.3 and 1.5 ersions) Low Standby Current: 0.1μA Typical Low Quiescent Current: 25μA Typical High Ripple Rejection: 70dB Typical (f=1khz) Output Current: More Than 200mA (300mA Limit) Extremely Low Noise: 30μrms (10Hz to 100kHz) Excellent Line Regulation: 4m Typical Excellent Load Regulation: 12m Typical High Output oltage Accuracy: ±2% Excellent Line Transient Response and Load Transient Response Compatible with Low ESR Ceramic Capacitor (as Low as 1μF) Applications Mobile Phones, Cordless Phones Wireless Communication Equipment Portable Games Cameras, ideo Recorders Sub-board Power Supplies for Telecom Equipment Battery Powered Equipment SOT-23-3 SOT-23-5 CSP-4 Figure 1.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods may affect device reliability. Note 2: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature, T J(max), the junction-to-ambient thermal resistance, θ JA, and the ambient temperature, T A. The maximum allowable power dissipation at any ambient temperature is calculated using: P D(max) =(T J(max) - T A )/θ JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature.
