|Datasheet||Download LM333 datasheet
The is an adjustable 3-terminal negative voltage regulator capable of supplying in excess of -3.0A over an output voltage range to -32V. This regulator is exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the LM333 features internal current limiting, thermal shutdown and safe-area compensation, making them substantially immune to failure from overloads. The LM333 serves a wide variety of applications including local on-card regulation, programmable-output voltage regulation or precision current regulation. The is an ideal complement to the LM150/LM350 adjustable positive regulators.Features

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device outside of its stated operating conditions. Note 2: All limits are guaranteed at either room temperature (standard type face) or at temperature extremes (bold typeface) by production testing or correlation techniques using standard Statistical Quality Control (SQC) methods. Note 3: Unless otherwise specified: |VIN - VOUT| = 5V, IOUT = 0.5A, PDISS 30W. Note 4: Load and line regulation are measured at constant junction temperature, using low duty cycle pulse testing (output voltage changes due to heating effects are covered by the Thermal Regulation specification). For the TO-3 package, load regulation is measured on the output pin, 1/8" below the base of the package. Note 5: The output current of the LM333 is guaranteed 3A in the range 3V |VIN - VOUT| 10V. For the range 10V |VIN - VOUT| 15V, the guaranteed minimum output current is equal to: 30/ (VIN - VOUT).

*When CL is larger than 20 µF, D1 protects the LM333 in case the input supply is shorted. **When C2 is larger than 10 µF and -VOUT is larger than -25V, D2 protects the LM333 in case the output is shorted. ***In case VOUT is shorted to a positive supply, D3 protects the LM333 from overvoltage, and protects the load from reversed voltage.
