DESCRIPTION
The LM29150 are high current, high accuracy, low-dropout voltage regulators. Using process with a PNP pass
element, these regulators feature 350mV (full load) dropout voltages and very low ground current.
These devices also find applications in lower current, low dropout-critical systems, where their tiny dropout
voltage and graound current values are important attributes.
The LM29150 are fully protected against over current faults, reversed input polarity, reversed lead insertion,
over temperature operation, and positive and negative transient voltage spikes. Five pin fixed voltage versions
feature logic level ON/OFF control and an error flag which signals whenever the output falls out of regulation.
On the LM29150 and LM29152, the ENABLE pin may be tied to Vin if it is not required for ON/OFF control.
The LM29150 are available in 3- and 5- pinTO-220 and surface mount TO-263 packages.
