LM333
3-Ampere Adjustable Negative Regulator
General Description
The LM333 is an adjustable 3-terminal negative voltage
regulator capable of supplying in excess of −3.0A over an
output voltage range of −1.2V to −32V. This regulator is
exceptionally easy to apply, requiring only 2 external resis-
tors to set the output voltage and 1 output capacitor for
frequency compensation. The circuit design has been opti-
mized for excellent regulation and low thermal transients.
Further, the LM333 features internal current limiting, thermal
shutdown and safe-area compensation, making them sub-
stantially immune to failure from overloads.
The LM333 serves a wide variety of applications including
local on-card regulation, programmable-output voltage regu-
lation or precision current regulation. The LM333 is an ideal
complement to the LM150/LM350 adjustable positive regu-
lators.

*Control regulator must have the largest VREF
**Full output current requires 5V≤|VIN–VOUT| ≤10V. At higher input-output voltages, load current will be less (see guaranteed curves)
