Description : ULTRA LOW drop-LOW NOISE BICMOS VOLTAGE REGULATORS LOW ESR CAPACITORS COMPATIBLE View

Description
The LD3985xx provides up to 150 mA, from 2.5 V to 6 V input VOLTAGE. The ULTRA LOW drop-VOLTAGE, LOW quiescent current and LOW NOISE make it suitable for LOW power applications and in battery powered systems. Regulator ground current increases only slightly in dropout, further prolonging the battery life. Power supply rejection is better than 60 dB at LOW frequencies and starts to roll off at 10 kHz. High power supply rejection is maintained down to LOW input VOLTAGE levels common to battery operated circuits. Shutdown logic control function is available, 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 LD3985xx is designed to work with LOW ESR ceramic CAPACITORS. Typical applications are in mobile phone and similar battery powered wireless systems.

Description : Very LOW drop and LOW NOISE VOLTAGE regulator LOW ESR CAPACITORS COMPATIBLE, with inhibit function View

Description
The LD2985A/Bxx is a 150 mA 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.

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, CBYP = 10 nF, connected between bypass pin and GND reduce the NOISE to 30 µVrms.
Typical application are in cellular phone, palmtop laptop computer, personal digital assistant (PDA), personal stereo, camcorder and camera.
