YB1210 – 300mA

Ultra-Low-Noise, High PSRR LDO Regulator

Description

Features

High Accuracy +-2% Output Voltage

Ultra-Low-Noise Low-Drop-Out

Regulator with 1.8/2.5/2.6/2.8/3.0V/3.3V

Preset Outputs

Stable with 0.47µF Ceramic Capacitor

for Any Load

Allowable Output Current: 300mA

Low Quiescent Current: ~90µA

450mV Dropout at 250mA Load (3.3V)

Only Need Input and Output Capacitors

Power Saving Shutdown Mode (<1µA)

Thermal Protection Shutdown

Built-In Internal Soft-Start

The YB1210 family consists of a series of

300mA ultra-low-noise, low dropout (LDO)

linear regulators especially designed for

battery-powered

and

wireless

applications. The YB1210 regulator

achieves a low 450mV dropout at 250mA

load current of 3.3V output, ultra-low output

voltage noise of 15µVrms and PSRR of

57dB at 1KHz.

The YB1210 regulators are also optimized

to work with low-ESR and low cost ceramic

capacitors reducing the amount of board

space critical in hand-held devices. The

YB1210 requires only 0.47 µF output

capacitor for stability with any load. The

YB1210 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

Other features include high output voltage

accuracy and current limiting protection.

The YB1210 regulators are available in

SOT-23 / SOT-25 / SOT-89 packages.
