TLV717xx TLV717xxP www.ti.com SBVS176A – OCTOBER 2011 – REVISED APRIL 2012 APPLICATION INFORMATION The TLV717xx belongs to a new family of next-generation value low-dropout (LDO) regulators. These devices consume low quiescent current and deliver excellent line and load transient performance. These characteristics, combined with low noise, very good PSRR with little (VIN – VOUT) headroom, make this family of devices ideal for RF portable applications. This family of regulators offers current foldback.

TLV717xx TLV717xxP SBVS176A – OCTOBER 2011 – REVISED APRIL 2012 www.ti.com DROPOUT VOLTAGE The TLV717xx uses a PMOS pass transistor to achieve low dropout. When (VIN – VOUT) is less than the dropout voltage (VDO), the PMOS pass device is in the linear region of operation and the input-to-output resistance is the RDS(ON) of the PMOS pass element. VDO scales approximately with output current because the PMOS device behaves like a resistor in dropout.
