Description

The SI9185DMP-30-T1 is designed as a 500mA CMOS LDO (low dropout) voltage regulator. The SI9185DMP-30-T1 device features ultra low ground current and dropout voltage to prolong battery life in portable electronics. It offers line/load transient response and ripple rejection superior to that of bipolar or BiCMOS LDO regulators, and is designed to drive lower cost ceramic, as well as tantalum, output capacitors.

SI9185DMP-30-T1 has thirteen features. (1)Input voltage 2V to 6V. (2)Low 150mV dropout at 500mA load. (3)Guaranteed 500mA output current. (4)Uses low ESR ceramic output capacitor. (5)Fast load and line transient response. (6)Only 100uVrms noise with noise bypass capacitor. (7)1uA maximum shutdown current. (8)Built-in short circuit and thermal protection. (9)Out-of-regulation error flag (power good POR). (10)Fixd 3.0V or adjustable output voltage options. (11)Other output voltages available by special order. (12)1.1W power dissipation. (13)Thin, thermally enhanced MLP33 powerPAK package. Those are all the main features.

Some absolute maximum ratings of SI9185DMP-30-T1 have been concluded into several points as follow. (1)Its input voltage would be 6.5V. (2)Its /SD input voltage would be from -0.3V to Vin. (3)Its output current would be 500mA continuous, short circuit protected. (4)Its output voltage would be from -0.3V to Vo(nom)+0.3V. (5)Its maximum junction temperature would be 150°C. (6)Its storage temperature range would be from -55°C to 150°C. (7)Its ESD (human body model) would be 2kV. (8)Its power dissipation would be 2.5W. (9)Its thermal impedance would be 50°C/W for junction to ambient and would be 4°C/W for junction to case. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SI9185DMP-30-T1 are concluded as follow. (1)Its output voltage range would be min 1.215V and max 5V. (2)Its output voltage accuracy would be min -1.5%Vo(nom) and max 1.5%Vo(nom) for room. (3)Its feedback voltage (ADJ version) would be min 1.191V and typ 1.215V and max 1.239V for room. And so on.
