Linear & Switching Voltage Regulators

LM2937ES-5.0 Description

The LM2937ES-5.0 from Texas Instruments is a fixed-output, low-dropout (LDO) linear voltage regulator designed to deliver a stable 5V output with a maximum current of 500mA. It operates over a wide input voltage range of up to 26V, making it suitable for applications requiring robust voltage regulation in harsh environments. The device features a low dropout voltage of 1V at 500mA, ensuring efficient performance even when the input voltage is close to the output level. Packaged in a DDPAK/TO-263 surface-mount form factor, it is ideal for space-constrained designs. With a quiescent current of 10mA and a maximum supply current of 20mA, it balances power efficiency with reliable operation.
