ZHCSHZ4D April 2018 – October 2023 TLV758P
PRODUCTION DATA
The TLV758P uses a PMOS pass transistor to achieve low dropout. When (VIN – VOUT) is less than the dropout voltage (VDO), the PMOS pass transistor is in the linear region of operation and the input-to-output resistance is the RDS(ON) of the PMOS pass transistor. VDO scales approximately with output current because the PMOS pass transistor behaves like a resistor in dropout mode. As with any linear regulator, PSRR and transient response degrade as (VIN – VOUT) approaches dropout operation.
