LM2594M-5.0/NOPB DC/DC step-down switching regulator, fixed, 500 mA, 5 Vout, SO-8

SIMPLE SWITCHER® 150 KHz, 500mA Low Component Count Step-Down Regulator

Description The LM2594xx series of regulators are monolithic integrated circuits that provide all theactive functions for a step-down (buck) switching regulator, capable of driving a 0.5-A load withexcellent line and load regulation. These devices are available in fixed output voltages of 3.3 V,5 V, 12 V, and an adjustable output version, and are packaged in a 8-pin PDIP and a 8-pinsurface-mount SOIC package. Requiring a minimum number of external components, these regulators are simple to use andfeature internal frequency compensation, a fixed-frequency oscillator, and improved line and loadregulation specifications.

Features - 3.3-V, 5-V, 12-V, and adjustable output versions - Adjustable version output voltage range: 1.2 V to 37 V (57-V for the HV version), ±4% maximum over line and load conditions - Available in 8-pin surface-mount SOIC and 8-pin PDIP packages - Ensured 0.5-A output current - Input voltage range up to 60 V - Requires only four external components - 150-kHz Fixed-frequency internal oscillator - TTL shutdown capability - Low power standby mode, IQ typically 85 µA - High efficiency - Uses readily-available standard inductors - Thermal shutdown and current-limit protection

Applcations: - Simple high-efficiency step-down (buck) regulator - Efficient preregulator for linear regulators - On-card switching regulators - Positive-to-negative convertor
