APU8836-HF-3
Description
The APU8836 device is an efficient linear voltage
regulator with better than 2% initial voltage accuracy,
very low dropout voltage and very low ground current,
designed especially for hand-held, battery-powered
applications. Other features of the device are TTL
compatible enable/shutdown control input, current-
limiting and thermal shutdown.
The APU8836-HF-3 is available as an adjustable
output voltage regulator in a small RoHS-compliant
halogen-free SOT-23-5 package.

Note 1: Low duty cycle pulse testing with Kelvin connections is required in order to maintain accurate data.
Note 2: Dropout voltage is defined as the minimum differential voltage between VIN and VOUT required to maintain regulation at VOUT.
It is measured when the output voltage drops 1% below its nominal value.
Note 3: Ground current is the regulator quiescent current plus the pass transistor current. The total current from the supply is the
of the load current plus the ground pin current.

VOUT
APU8836-HF-3
The input pin of the regulator. Typically a large storage capacitor is connected from
this pin to ground to ensure that the input voltage does not sag below the minimum
drop out voltage during the load transient response. This pin must always be higher
than VOUT by at least the amount of the dropout voltage and some margin in order for
the device to regulate properly.
Ground pin. This pin must be connected to the lowest potential in the system and all
other pins must be at higher potential with respect to this pin.
Enable pin. A low signal or left open on this pin shuts down the output. This pin must
be tied HI or to VIN for normal operation.
A resistor divider from this pin to the VOUT pin and ground sets the output voltage. To
minimize the error due to the error amplifier, select the values of the resistor dividers
to be less than 10kΩ.
The output of the regulator. A capacitor with a minimum value of 2.2µF
of 1Ω must be connected from this pin to ground to ensure stability.
