Datasheet HT75Rxx-7 (Holtek) - 6

HT75Rxx-7 30V, 150mA TinyPowerTM LDO with Protections Symbol Parameter Test Conditions Min. Typ. Max. Unit
ISHORT Output Short Current VIN=12V, force VOUT=0V — 150 — mA TSHD Shutdown Temperature — — 150 — oC TREC Recovery Temperature — — 125 — oC VIH CE Input High Threshold VOUT+1V ≤ VIN ≤ 30V 2.0 — — V VIL CE Input Low Threshold VOUT+1V ≤ VIN ≤ 30V — — 0.6 V RDIS Discharge Resistor VCE=0V, measure at VOUT — 300 — Ω Note: The dropout voltage is defined as the input voltage minus the output voltage that produces a 2% change in the output voltage from the value at VIN=VOUT+2V with a fixed load.
