APPLICATIONS
The APU8850 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 APU8850 is available in fixed and adjustable
output voltage versions in a small SOT-23-5L, TSOT-23-5L,
J-lead 2021-8, ESOP-8 & SOT-89 package.
