AT1203
Low Noise, 300mA CMOS LDO Regulator
General Description
Features
• SOT-23-5,SOT-23-3 and SOT89 Packages
• Low Dropout Voltage：350mV
• Low Output Noise
The AT1203 is an ultra-low noise, low dropout
voltage, low quiescent current CMOS LDO,
capable of delivering up to 300mA.
• Low Quiescent Current：90µA
• Guaranteed 300mA Output Current
• Fixed Output Voltage：1.5V,1.8V, 1.9V, 2.5V,
2.8V, 3.0V,3.3V, 4.2V and 5.0V
• Built-In Current Limit
This LDO provides factory preset 1.5V,1.8V, 1.9V,
2.5V, 2.8V, 3.0V, 3.3V,4.2V and 5.0V fixed output
voltage.
That is ideally suited for input powered
（ 2.5V~5.5V ） from Li-Ion, NiCd, NiMH,
Alkaline battery or USB-Base power system.
• Built-In Thermal Shutdown
• Built-In LDO ON/OFF Control
Designed with an internal P-channel MOSFET
pass elements maintain ultra-low supply current
throughout the whole entire operating range.
Applications
• Cellular Phones
The AT1203 is protected with current limit,
ON/OFF control and thermal shutdown.
• Wireless Devices
• Portable Electronics
• Battery Powered Systems

Note1：The dropout voltage is measured from VIN to VOUT when VOUT is 2% below its nominal
value. The nominal output voltage is measured from VOUT to GND when VIN is 1V greater
than VOUT. Defined only for VOUT ≥ 2.5V.
Note2：For VOUT < 2V, VIN must be above 2.5V.
