SLVS329C – JUNE 2001 – REVISED MARCH 2004
The TPS756xx 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 TPS75601 (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
such a way to minimize/avoid noise pickup. Adding RC networks between FB terminal and V
O
to filter noise is
not recommended because it may cause the regulator to oscillate.

terminal is an input to the regulator.

(1) 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.

(1) For both packages, the R
ΘJA
values were computed using JEDEC high K board (2S2P) with 1 ounce internal copper plane and ground
plane. There was no air flow across the packages.
(2) R
ΘJA
was computed assuming a vertical, free standing TO-220 package with pins soldered to the board. There is no heatsink attached
to the package.
(3) R
ΘJA
was computed assuming a horizontally mounted TO-263 package with pins soldered to the board. There is no copper pad
underneath the package.
