LTC2903-1

Precision Quad Supply

Monitor in 6-Lead SOT-23

FEATURES

DESCRIPTIO

The LTC^®2903-1 monitors up to four supply voltages. The

common reset output remains low until all four inputs

have been in compliance for 200ms. Voltage thresholds

maintain ±1.5% accuracy over temperature (with respect

to the monitored voltage). The LTC2903-1 features an

open-drain RST output with a weak internal pullup.
