Low Dropout Regulator (5V Output LDO)

-40ºC < TJ < 115ºC; all voltages are with respect to ground (GND);

positive current flows into the pin, NORMAL operating mode, if

not otherwise mentioned. The LDO block is a linear voltage

regulator, which provides a regulated 5V.

LDO Parameters

Note(s) and/or Footnote(s):

1. In NORMAL mode, maximum load current will be 50mA. After internal thermal shutdown, current limit is 20mA.

2. The LDO is disabled in SLEEP mode.
