SiP21110

Vishay Siliconix

250-mA Adjustable, Low Dropout Regulator

DESCRIPTION

FEATURES

•

TSOT23-5L (3.05 mm x 2.85 mm x 1.0 mm)

1.0 % output voltage accuracy at 25 °C

Low dropout voltage: 225 mV at 250 mA

35 µA (typical) ground current in 1 mA load

1 µA maximum shutdown current at 85 °C

Output auto discharge in shutdown mode

The SiP21110 BiCMOS 250 mA LDO voltage regulators are

the perfect choice for low battery operated low powered

applications. An ultra low ground current and low dropout

voltage of 225 mV at 250 mA load helps to extend battery life

for portable electronics.

RoHS

COMPLIANT

The SiP21110 output is adjusted with an external resistor

network.

Built-in short circuit (500 mA typical) and thermal

protection (160 °C typical)

The regulator allows stable operation with very small ceramic

output capacitors, reducing board space and component

cost. It is designed to maintain regulation while delivering

330 mA typical peak current upon turn-on. During start-up,

an active pull-down circuit improves the output transient

response and regulation. In shutdown mode, the output

automatically discharges to ground through a 100 Ω NMOS.

•

- 40 °C to + 125 °C junction temperature range for

operation

Uses low ESR ceramic capacitors

Compliant to RoHS Directive 2002/95/EC

•

APPLICATIONS

•

Cellular phones, wireless handsets

PDAs

MP3 players

Digital cameras

Pagers

The SiP21110 are available in TSOT23-5L packages for

operation over the industrial operation range (- 40 °C to

+ 85 °C).

Wireless modem

• Noise-sensitive electronic systems
