LM137 and LM337 adjustable negative voltage regulators

The LM137 and LM337 are adjustable 3-terminal negative voltage regulators capable of supplying in excess of −1.5A over an output voltage range of −1.2V to −37V.

MAX17031 dual step-down power-supply (SMPS) controller

Using the MAX17031 dual step-down power-supply (SMPS) controller can be designed a very simple high efficiency power supply circuit with synchronous rectification, intended for main 5V/3.3V power generation in battery-powered systems.
Low-side MOSFET sensing provides a simple low-cost, highly efficient current sense for valley current-limit protection. Combined with the output overvoltage and undervoltage protection features, this current limit ensures robust output supplies.

LM150 voltage regulator power supply

The LM150 is a positive voltage regulator capable of supplying 3A over a 1.2V to 33V output range.
