GENERAL DESCRIPTION
The ADP320 200 mA triple output LDO combines high PSRR, low
noise, low quiescent current, and low dropout voltage in a voltage
regulator ideally suited for wireless applications with demanding
performance and board space requirements.
The low quiescent current, low dropout voltage, and wide input
voltage range of the ADP320 triple LDO extend the battery life of
portable devices. The ADP320 triple LDO maintains power supply
rejection greater than 60 dB for frequencies as high as 100 kHz

Figure 1. Typical Application Circuit
LDO offers much lower noise performance than competing LDOs
without the need for a noise bypass capacitor.
The ADP320 triple LDO is available in a miniature 16-lead
3 mm × 3 mm LFCSP package and is stable with tiny 1 μF ±30%
ceramic output capacitors, resulting in the smallest possible board
area for a wide variety of portable power needs.
The ADP320 triple LDO is available in output voltage combin-
ations ranging from 0.8 V to 3.3 V and offers over current and
thermal protection to prevent damage in adverse conditions.

1 Based on an end-point calculation using 1 mA and 200 mA loads.
2 Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This applies only for output
voltages above 1.8 V.
3 Start-up time is defined as the time between the rising edge of ENx to VOUTx being at 90% of its nominal value.
4 Current-limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a 3.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 3.0 V, or 2.7 V.

1 The minimum input and output capacitance should be greater than 0.70 μF over the full range of operating conditions. The full range of operating conditions in the
application must be considered during device selection to ensure that the minimum capacitance specification is met. X7R and X5R type capacitors are recommended,
Y5V and Z5U capacitors are not recommended for use with LDOs.
