600mA LOW DROPOUT LINEAR REGULATOR
General Description
Features
The AP2317 is a series of low dropout three-terminal
regulators with a dropout of 1.1V at 600mA output current.
·
·
This product has been optimized for low voltage where
transient response and minimum input voltage are critical. The AP2317 provides current limit and thermal
shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within
±1%. On-chip thermal shutdown provides protection
against any combination of overload and ambient temperatures that would create excessive junction temperatures.
Low Dropout Voltage: 1.1V at 600mA Output
Current
Output Noise from 10Hz to 10KHz: 0.003% of
VOUT
·
PSRR at IOUT=300mA and f=120Hz: 75dB
·
·
·
Output Voltage Accuracy: ± 1%
On-chip Thermal Shutdown
Maximum Quiescent Current: IQMAX=5mA
·
·
ESD (Human Body Model): 3.5KV
Operation Junction Temperature: -40 to 125oC
Applications
The AP2317 is available in 2.5V and 3.3V versions.
The fixed versions integrate the corresponding resistor
divider. It is also available in an adjustable version
which can set the output voltage with two external
resistors.
·
·
·
·
·
The AP2317 is available in the industry standard SOT89-3, SOT-223 and TO-263-3 (for 3.3V only) power
packages.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
Note 2: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the device outside of its operating ratings. The maximum allowable power dissipation is a
function of the maximum junction temperature, TJ(max), the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD(max)=(TJ(max) TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will
go into thermal shutdown.
