SLVS330D – JUNE 2001 – REVISED MARCH 2004

The TPS758xx family includes four fixed-output voltage regulators (1.5 V, 1.8 V, 2.5 V, and 3.3 V), and an

adjustable regulator, the TPS75801 (adjustable from 1.22 V to 5 V). The bandgap voltage is typically 1.22 V.

The EN terminal is an input which enables or shuts down the device. If EN is a low voltage level (<0.7 V), the

device will be in shutdown or sleep mode. When EN goes to a high voltage level (>2 V), the device will be

enabled.

FB is an input terminal used for the adjustable-output option and must be connected to the output terminal either

directly, in order to generate the minimum output voltage of 1.22 V, or through an external feedback resistor

divider for other output voltages. The FB connection should be as short as possible. It is essential to route it in

not recommended because it may cause the regulator to oscillate.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
