ZHCSHZ7A April 2018 – December 2018 TLV759P
PRODUCTION DATA.
The TLV759P 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 mode. As with any linear regulator, PSRR and transient response degrade as (VIN – VOUT) approaches dropout operation.
