General Description

The LMS5258 is a µCap, precise CMOS voltage regulator with power good output.

It provides up to 150mA and consumes a typical of 10nA in shutdown mode. The LMS5258 output stage is designed with a push pull output for faster transient response.

The LMS5258 is optimized to work with low value, low cost ceramic capacitors. The output typically require only 1µF of output capacitance for stability. The enable pin can be tied to VIN for easy device layout.

The LMS5258 is designed for portable, battery powered equipment applications with small space requirements.

The LMS5258 is available in a 5-pin SOT-23 package. Performance is specified for the -40°C to +125°C temperature range and is available in a fixed 1.2V. For other output voltage options, please contact National Semiconductor.
