LD2982AM25R General Description

The LD2982 is a 50mA fixed output voltage regulator. The ultra low drop voltage and the low quiescent current make them particularly suitable for low noise, low power applications, and in battery powered systems. In sleep mode quiescent current is less than 1µA when INHIBIT pin is pulled low. Shutdown Logic Control Function is available on pin 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.

An external capacitor C_BYP=10nF connected between bypass pin and GND reduce the noise to 30µVrms.

Typical application are in cellular phone, palmtop/laptop computer, personal digital assistant (PDA),personal stereo, camcorder and camera.

LD2982AM25R Maximum Ratings

Symbol	Parameter	Value	Unit
V_I	DC Input Voltage	16	V
V_INH	INHIBIT Input Voltage	16	V
I_O	Output Current	Internally Limited
P_tot	Power Dissipation	Internally Limited
T_stg	Storage Temperature Range	-65 to +150
T_op	Operating Junction Temperature Range	-40 to +125

Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these condition is not implied.
