The RESET output remains asserted for the factory programmed delay • Precision Supply Voltage Monitor 1.8 V, 2.5 V, time after the SENSE or VDD return above its 2.7 V, 3 V, 3.3 V, 5 V, and Adjustable threshold. • Manual Reset Input (Except TPS3801-01) The TPS380x devices, except the TPS3801-01, • Temperature Range: –40°C to +85°C incorporate a manual reset input (MR). A low level at MR causes RESET to become active. APPLICATIONS The TPS380x uses a precision reference to achieve • Applications Using DSPs, Microcontrollers, or an overall threshold accuracy of 2%—2.5%. These Microprocessors devices are available in a 5-pin SC-70 package, • Wireless Communication Systems which is only about half the size of a 5-pin SOT-23 • Portable/Battery-Powered Equipment package. • Programmable Controls The TPS380x devices are fully specified over a • Intelligent Instruments temperature range of –40°C to +85°C. • Industrial Equipment • Notebook/Desktop Computers • Automotive Systems 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
