Data Sheet

AS1361/AS1362

150mA/300mA, Ultra-Low-Noise, High-PSRR

Low Dropout Regulators, with POK

1 General Description

2 Key Features

ꢀ

Preset Output Voltages: 1.5 to 4.5V (in 50mV steps)

The AS1361/AS1362 are ultra-low-noise, low-dropout

linear regulators specifically designed to deliver up to

150/300mA continuous output current, and can achieve

a low 140mV dropout for 300mA load current. The LDOs

are designed and optimized to work with low-cost, small-

capacitance ceramic capacitors.

Output Noise: 9µVRMS @ 100Hz to 100kHz

Power-Supply Rejection Ratio: 92dB @ 1kHz

Low Dropout: 140mV @ 300mA Load

Power-OK Output

The devices are available as the standard products

listed in Table 1.

Stable with 1µF Ceramic Capacitor for any Load

Extremely-Low Quiescent Current: 40µA

Excellent Load/Line Transient

An integrated P-channel MOSFET pass transistor allows

the devices to maintain extremely low quiescent current

(40µA).

Overcurrent and Thermal Protection

TSOT23 6-pin Package

The AS1361/AS1362 uses an advanced architecture to

achieve ultra-low output voltage noise of 9µVRMS and a

power-supply rejection-ratio of better than 80dB (up to

10kHz).

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.

An active-Low, open-drain power-ok output indicates if

the output voltage is within regulation.

The AS1361/AS1362 requires only 1µF output capacitor

for stability at any load. When the LDO is disabled, cur-

rent consumption drops below 500nA.

The devices are available in a TSOT23 6-pin package.
