YB1231 – HV600mA

Low-Noise LDO Regulator

Features

Description

2.0% Accuracy Output Voltage

Output Voltage range 3.2V~4.5V

Low-Noise Low-Drop-Out

Stable with 2.2μF Ceramic Capacitor for

Any Load

Typical Output Current : 600 mA

Low Quiescent Current : ~100μA

440mV Dropout at 600mA Load (4.5V)

Thermal Protection Shutdown

Built-In Internal Soft-Start

The YB1231 is a series of ultra-low-noise,

low dropout (LDO) linear regulators with

2.0% output voltage accuracy. The YB1231

regulators achieve a low 440mV dropout at

600mA load current of 4.5V output and are

available in voltages ranging from 3.2V to

4.5V with 0.1 V per step (custom voltage is

considerable at request).

The YB1231 regulators are optimized to

work with low-ESR and low cost ceramic

capacitors, reducing the amount of board

space critical in hand-held devices. The

YB1231 requires only 2.2 μF output

capacitor for stability with any load and

consumes less than 1μA in shutdown

mode.

Output Short-circuit Current Limit

Protection

Green package (RoHS) available

Applications

PDA, Palmtops and Notebook

Computers

DSC, Handset Camera Modules

PCMCIA Cards, PC Cameras

USB Based Portable Devices (MP3, PMP)

GSM/GPRS/3G RF Transceiver Modules

Wireless LANs

Built-in thermal shutdown and short-circuit

protect offer secure protection against fault

operation. The YB1231 regulators are

available in SOT-23 / SOT-25 / SOT-89

packages.

Bluetooth Portable Radios
