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 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2017-08-06 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2018-05-04 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2018-12-17 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2019-04-02 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2021-04-25 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2022-11-30 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2023-01-07 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2023-03-20 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2023-10-22 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2025-12-27 https://elecena.pl/product/9716445/lm2594m-3-3-nopb-dc-dc-step-down-switching-regulator-fixed-500-ma-3-3-vout-so 2026-02-05
