NCP1086
1.5 A Adjustable
and 3.3 V Fixed Output
Linear Regulator
The NCP1086 linear regulator provides 1.5 A at 3.3 V or adjustable
output voltage. The adjustable output voltage device uses two external
resistors to set the output voltage within a 1.25 V to 5.5 V range.
The regulators is intended for use as post regulator and
microprocessor supply. The fast loop response and low dropout
voltage make this regulator ideal for applications where low voltage
operation and good transient response are important.
The circuit is designed to operate with dropout voltages less than
1.4 V at 1.5 A output current. Device protection includes overcurrent
and thermal shutdown.
This device is pin compatible with LT1086 family of linear
regulators and has lower dropout voltage.
The regulators are available in TO鈥?20, surface mount D
2
PAK, and
SOT鈥?23 packages.
