BD7003NUX_11 Datasheet, PDF (1/14 Pages) Rohm – CMOS LDO Regulator for Portable Equipments Dual, Low-Dropout Linear Regulator

CMOS LDO Regulator for Portable Equipments
Dual, Low-Dropout
Linear Regulator
BD7003NUX, BD7004NUX
No.12020ECT09
●Descriptions
The BD7003NUX, BD7004NUX are dual channels, 300mA low-dropout voltage regulator output at each channel. The output
voltage range is from 1.2V to 3.3V by operating range from 2.5V to 5.5V. The output voltages, VOUT1 and VOUT2, are
determined at power up by the state of P1 and P2(see the table of “Output-Voltage Programming”). The BD7003NUX,
BD7004NUX offer 1.8% accuracy and low-dropout. The shutdown current is near the zero current which is suitable for
battery powered device. The BD7003NUX, BD7004NUX are mounted on VSON008X2020(2.0mmX2.0mmX0.6mm), which
contributes to the space-saving design of set.
●Features
1) 2-channel 300mA, CMOS-type LDOs.
2) Pin-Programmable Output Voltage.
(9 steps adjustable VO；See the Table of “Output-Voltage Programming”.)
3) LDOs Power ON/OFF Enable Control.
4) 2.0mm×2.0mm Package.
5) Small Ceramic Output Capacitors(1μF).
6) Equipped with Over Current Limiter and Thermal Shutdown Circuit(TSD) .
●Applications
Battery-powered portable equipment, etc.
