TLV712xx www.ti.com SBVS150A – SEPTEMBER 2010 – REVISED JANUARY 2011 APPLICATION INFORMATION GENERAL DESCRIPTION The TLV712xx belongs to a new family of next-generation value LDO regulators. These devices offer sub-bandgap output voltages; that is, output voltages from 1.2 V all the way down to 0.7 V. These devices consume low quiescent current and deliver excellent line and load transient performance.

TLV712xx SBVS150A – SEPTEMBER 2010 – REVISED JANUARY 2011 www.ti.com DROPOUT VOLTAGE The TLV712xx uses a PMOS pass transistor to achieve low dropout. For the complete output voltage range of 0.7 V to 1.2 V, the device can supply 300 mA with a rated minimum input voltage of 2.0 V. Note that the dropout voltage specification is not relevant for the TLV712xx family of devices because the output voltage range of the device does not exceed 1.2 V and the minimum input voltage for the device is 2.0 V.
