Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM828M5

LM828M5

Voltage Regulators - DC DC Switching Regulators Overview

The LM828M5 is a CMOS charge-pump voltage converter manufactured by Texas Instruments. It inverts positive input voltages ranging from +1.8V to +5.5V into corresponding negative outputs. The device utilizes two external capacitors to deliver up to 25mA of output current while operating at a switching frequency of 12kHz. Designed for battery-powered applications, it features an operating current of only 40µA, ensuring efficiency greater than 96% under typical loads. The component is housed in a compact SOT-23-5 package and operates within a temperature range of -40°C to +85°C.
