LP2983 Micropower 150 mA Voltage Regulator in SOT-23 Package For Output Voltages ≤ 1.2V Designed for Use with Very Low ESR Output Capacitors
The LP2983 is a fixed‑output, 150 mA micropower regulator designed for output voltages up to 1.2 V. It uses an optimized VIP™ (Vertically Integrated PNP) process to achieve low ground‑pin current, 1 % output‑voltage tolerance (A‑grade), and stability with ceramic capacitors whose ESR can be zero.
Typical applications include cellular phones, PDAs, laptops and other portable electronics. The device is supplied in a SOT‑23 (M5) package, with ordering information and detailed electrical characteristics provided for designers.
| Ground Pin Current | 825 µA @ 150 mA load |
|---|---|
| Output Voltage Accuracy | 1 % tolerance (A‑grade) |
| Supply Voltage Range | Up to 16 V |
| Low Output Impedance (Zout) | 0.39 Ω typical (10 Hz‑1 MHz) |
| Operating Temperature Range | -40 °C to +125 °C |
| Package | SOT‑23 (M5) Small Outline Package |
| Maximum Output Current | 150 mA |
The regulator draws about 825 µA from the ground pin when delivering a 150 mA load.
Driving the ON/OFF input low shuts the regulator off; if the feature is not used, tie the input to Vout to keep it on.
The regulator can tolerate an input voltage up to 16 V.
