| Download |  Technical Datasheet |
The LM337T is an adjustable 3-terminal Negative Voltage Regulator, capable of supplying in excess of -1.5A over an output voltage range of -1.2V to -37V. 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 LM137 series features internal current limiting, thermal shutdown and safe-area compensation, making them virtually blowout-proof against overloads. The LM337T serves a wide variety of applications including local on-card regulation, programmable-output voltage regulation or precision current regulation. The LM337T is ideal complements to the LM117/LM317 adjustable positive regulators.

Texas Instruments TPS2551QDBVRQ1
The TPS2551QDBVRQ1 is a Power Distribution Switch intended for applications in which heavy capacitive loads and short circuits are likely to be encountered. The current-limit threshold is user adjustable between 100mA and 1.1A via an external resistor. The power-switch rise and fall times are controlled to minimize current surges during switching. The device limits the output current to a desired level by switching into a constant-current mode when the output load exceeds the current-limit threshold or a short is present. An internal reverse-voltage detection comparator disables the power-switch in the event that the output voltage is driven higher than the input to protect devices on the input side of the switch. The FAULT logic output asserts low during both overcurrent and reverse-voltage conditions.
- 2µS Typical fast overcurrent response
- Reverse input-output voltage protection
- Deglitched fault report
- 1µA Maximum standby supply current

Infineon IFX78M05ABTFATMA1
The IFX78M05 monolithic 3-terminal positive voltage regulator employs internal current-limiting, thermal shutdown and safe-area compensation, making it extremely robust. The IFX78M05 is available in a fixed 5V version and is capable of delivering an output current of 0.5 A. This regulator can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. This linear voltage regulator is designed for a wide variety of applications and suitable for use in harsh environments. The short-circuit current limit, limits the output current of the device. The safe-area protection feature limits the internal power dissipation, in case the internal power dissipation becomes too high, the thermal shutdown implemented prevents the device from overheating.
