Description

L99VR01 is a low dropout linear voltage regulator designed for automotive

applications available in SO-8 and in PowerSSO-12 packages. The LDO delivers

up to 200 mA of load current and consumes as low as 1 μA of quiescent current

when the regulator is disabled. The input is 40 V tolerant to withstand load dump,

while the operating input voltage range is between 2.15 V and 28 V. The L99VR01

can be configured, through SELx pins, to generate a fixed selectable output voltage

(0.8 V; 1.2 V; 1.5 V; 1.8 V; 2.5 V; 2.8 V; 3.3 V or 5 V). High output voltage

accuracy (±2%) is kept over wide temperature range, line and load variation. The

L99VR01 features enable, reset, autonomous watchdog, advanced thermal warning,

fast output discharge and IShort control (IShort control, autonomous watchdog and

advanced thermal warning are available only for the L99VR01J). The regulator output

current is internally limited so that the device is protected against short-circuit and

overload, besides it features over temperature protection; the short current value

is configurable by an external resistance in the L99VR01J version. The L99VR01

can operate both in post regulation, attached to a pre-regulated voltage or directly

connected to battery.
