Texas Instruments TLV733P/TLV733P-Q1 Low-Dropout Regulators (LDOs)

Texas Instruments TLV733P/TLV733P-Q1 300mA Low-Dropout Regulators (LDOs) are ultra-small, low quiescent current LDOs that can source 300mA with good line and load transient performance. These devices provide a typical accuracy of 1%. The TLV733P/TLV733P-Q1 series is designed with modern capacitor-free architecture to ensure stability without an input or output capacitor. The removal of the output capacitor allows for a very small solution size and can eliminate inrush current at startup. However, the TLV733P/TLV733P-Q1 series is also stable with ceramic output capacitors if an output capacitor is necessary.

The TLV733P/TLV733P-Q1 also provides foldback current control during device power-up and enabling if an output capacitor is used. This functionality is especially important in battery-operated devices. The TLV733P/TLV733P-Q1 provides an active pull-down circuit to quickly discharge output loads when disabled. The Texas Instruments TLV733P-Q1 devices are AEC-Q100 qualified for automotive applications.
