Description

The TPS767D318PWPR is one member of the TPS767D318 series.The TPS767D318 family of dual voltage regulators offers fast transient response, low dropout voltages and dual outputs in a compact package and incorporating stability with 10-m F low ESR output capacitors.

Features of the TPS767D318PWPR are:(1)dual output voltages for split-supply applications;(2)output current range of 0 mA to 1.0 A per regulator;(3)3.3-V/2.5-V, 3.3-V/1.8-V, and 3.3-V/adjustable output;(4)dropout voltage typically 350 mV at 1 A;(5)ultra low 85 m A typical quiescent current;(6)dual open drain power-on reset with 200-ms delay for eachregulator.The TPS767D318PWPR dual voltage regulators is designed primarily for DSP applications.These devices can be used in any mixed-output voltage application, with each regulator supporting up to 1 A. Dual active-low reset signals allow resetting of core-logic and I/O separately.An input capacitor is not required; however, a ceramic bypass capacitor (0.047 pF to 0.1 m F) improves load transient response and noise rejection when the TPS767D318PWPR is located more than a few inches from the power supply. A higher-capacitance electrolytic capacitor may be necessary if large (hundreds of milliamps) load transients with fast rise times are anticipated.

The absolute maximum ratings of the TPS767D318PWPR can be summarized as:(1)input voltage range , VI:0.3 V to 13.5 V;(2)peak output current:internally limited;(3)operating virtual junction temperature range, Tj:40 C to 125 C;(4)storage temperature range Tstg:-65 to +150°C.Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. Exposure to absolute maximum conditions for extended periods may affect device reliability.The TPS767D318PWPR also features a shutdown mode that places the output in the high-impedance state(essentially equal to the feedback-divider resistance) and reduces quiescent current to under 2 m A. If the shutdown feature of TPS767D318PWPR is not used, EN should be tied to ground. Response to an enable transition is quick; regulated output voltage is typically reestablished in 120 m s.
