Datasheet

AS1374

200mA, Ultra-Low-Noise, High-PSRR, Dual

Low Dropout Regulators

1 General Description

2 Key Features

ꢀ

Preset Output Voltages: 1.2 to 3.6V (in 50mV steps)

Output Noise: 20µVRMS @ 100Hz to 100kHz

Power-Supply Rejection Ratio: 85dB @ 1kHz

Low Dropout: 120mV @ 200mA Load

Stable with 1µF Ceramic Capacitor for any Load

Guaranteed 200mA Output

The AS1374 is a ultra-low-noise, low-dropout linear reg-

ulator with two seperated outputs. Specifically designed

to deliver 200mA continuous output current at each out-

put pin. The LDOs can achieve a low 120mV dropout for

200mA load current and are designed and optimized to

work with low-cost, small-capacitance ceramic capaci-

tors.

An integrated P-channel MOSFET pass transistor allows

the devices to maintain extremely low quiescent current

(30µA).

Pull-Down Option in Shutdown (factory set)

Extremely-Low Quiescent Current: 30µA

Excellent Load/Line Transient

The AS1374 uses an advanced architecture to achieve

ultra-low output voltage noise of 20µVRMS and a power-

supply rejection-ratio of better than 85dB (@ 1kHz).

Two active-High enable pins allows to switch on or off

each output independently from each other.

Overcurrent and Thermal Protection

6-bump WLP Package

The AS1374 requires only 1µF output capacitor for sta-

bility at any load.

The device is available in a 6-bump WLP package.

3 Applications

The devices are ideal for mobile phones, wireless

phones, PDAs, handheld computers, mobile phone

base stations, Bluetooth portable radios and accesso-

ries, wireless LANs, digital cameras, personal audio

devices, and any other portable, battery-powered appli-

cation.
