nn MIL-PRF-38535 Class V Compliant The RH1965MK is a 0.9A low noise, low dropout linear
regulator with a PNP pass transistor, requiring only a
single supply for operation. Operating quiescent current
is 500μA, reducing to less than 1μA in shutdown. Output
voltage ranges from 1.2V to 19.5V. A small 10µF capacitor
on the output with an ESR of less than 1Ω is adequate to
ensure stability. Applications with large output load transients require a larger output capacitor value to minimize
output voltage change. Input circuitry ensures output safe
operating area with current limiting and thermal shutdown
protection. The rated dropout of an RH1965-based part …
