Overview
LD2980 Ultra low drop voltage regulators compatible with low ESR output capacitors Datasheet - production data Description SOT23-5L Features  Stable with low ESR ceramic capacitors  Ultra low dropout voltage (0.
12 V typ.
at 50 mA load, 7 mV typ.
at 1 mA load) The low drop voltage and the ultra low quiescent current make them suitable for low noise, low power applications and in battery powered systems.
The quiescent current in sleep mode is less than 1 µA when the INHIBIT pin is pulled low.
A shutdown logic control function is available on pin n° 3 (TTL compatible).
This means that when the device is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption.
The LD2980 is designed to work with low ESR ceramic capacitors.
Typical applications are cellular phone, laptop computer, personal digital assistant (PDA), personal stereo, camcorder and camera.
 Very low quiescent current (80 µA typ.
at no load in on mode; max 1 µ...
