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.
