150mA/300mA, Ultra-Low-Noise, High-PSRR
Low Dropout Regulators, with POK
Data Sheet
1 Generalwww.datasheet4u.com Description
2 Key Features
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.
The devices are available as the standard products
listed in Table 1.

150mA
Preset – 1.5 to 4.5V
AS1362
300mA
Preset – 1.5 to 4.5V
! Preset Output Voltages: 1.5 to 4.5V (in 50mV steps)
! Output Noise: 9µVRMS @ 100Hz to 100kHz
! Power-Supply Rejection Ratio: 92dB @ 1kHz
! Low Dropout: 140mV @ 300mA Load
! Power-OK Output
! Stable with 1µF Ceramic Capacitor for any Load
! Guaranteed 150/300mA Output
! 1.25V Internal Reference
! Extremely-Low Quiescent Current: 40µA
An integrated P-channel MOSFET pass transistor allows
the devices to maintain extremely low quiescent current
(40µA).
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).
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.

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.

Shutdown. Pull this pin low to disable the LDO.
Power-OK Output. Active-Low, open-drain output indicates if the output
voltage is within regulation.
0 = VOUT <94% VOUTNOM

Noise Bypass for Low-Noise Operation. Connect a 10nF capacitor from
this pin to OUT.
Note: This pin is shorted to GND in shutdown mode.
Regulated Output Voltage. Bypass this pin with a capacitor to GND. See
Capacitor Selection and Regulator Stability on page 10 for more details.
