Texas Instruments TPS7133QD Fixed LDO Voltage Regulator 3.77V to 10V 235mV Dropout 3.3Vout 500mAout SOIC-8

The TPS7133QD is a 3.3V fixed output low-dropout (LDO) Linear Regulator. An order of magnitude reduction in dropout voltage and quiescent current over conventional LDO performance is achieved by replacing the typical PNP pass transistor with a PMOS device. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and remains independent of output loading. These two key specifications yield a significant improvement in operating life for battery-powered systems. The device also features a sleep mode, applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to 0.5?A maximum at TJ = 25?C.

• 285?A Independent of load very low quiescent current
• 0.5?A Extremely low sleep-state current
• 2% Tolerance over specified conditions
• Output current range of 0 to 500mA
• Power good (PG) status output
