Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2595S-12/NOPB

LM2595S-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2595S-12/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments. It operates with an input voltage range of 4.5 V to 40 V and provides a fixed output of 12 V at up to 1 A. The device features a switching frequency of 150 kHz, typical quiescent current of 5 mA, and supports operation between -40°C and +125°C. Packaged in TO-263-5 for surface mount installation, it includes shutdown functionality.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-current switch rated for 1 A continuous load
Fixed 12 V output eliminates external resistor divider requirements
Built-in thermal shutdown protects against overheating conditions

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Pre-regulation stages for downstream linear regulators
Battery-powered equipment requiring efficient voltage conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the package designation matches the required TO-263-5 footprint for PCB layout compatibility. Ensure the fixed 12 V output aligns with system design requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required from a wide input voltage range. The 150 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 1 A output current meets the maximum load demand of the application circuit.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2595 series of SIMPLE SWITCHER regulators. It shares the same internal architecture as other variants in the family but differs in output configuration. The 'S' indicates the surface-mount TO-263 package, while '12' specifies the fixed output voltage.
