SBVS083C – JANUARY 2007 – REVISED MAY 2008 150mA, Low-Dropout Regulator, Ultralow-Power, IQ 500nA with Pin-Selectable, Dual-Level Output Voltage The VSET pin allows the end user to switch between two voltage levels on-the-fly through a 2 • Low I Q: 500nA microprocessor-compatible input. This LDO is • 150mA, Low-Dropout Regulator with designed specifically for battery-powered applications Pin-Selectable Dual Voltage Level Output where dual-level voltages are needed. With ultralow IQ (500nA), microprocessors, memory cards, and • Low Dropout: 200mV at 150mA smoke detectors are ideal applications for this device. • 3% Accuracy Over Load/Line/Temperature The ultralow-power and selectable dual-level output • Available in Dual-Level, Fixed Output Voltages voltages allow designers to customize power from 1.5V to 4.2V Using Innovative Factory consumption for specific applications. Designers can EPROM Programming now shift to a lower voltage level in a battery-powered • Available in an Adjustable Version from 1.22V design when the microprocessor is in sleep mode, to 5.25V or a Dual-Level Output Version further reducing overall system power consumption. The two voltage levels are preset at the factory • V SET Pin Toggles Output Voltage Between Two through a unique architecture using an EPROM. The Factory-Programmed Voltage Levels EPROM technique allows for numerous output • Stable with a 1.0µF Ceramic Capacitor voltage options between VSET low (1.5V to 4.2V) and • Thermal Shutdown and Overcurrent Protection VSET high (2.0V to 3.0V) in the fixed output version only. Consult with your local factory representative for • CMOS Logic Level-Compatible Enable Pin exact voltage options and ordering information; • Available in DDC (TSOT23-5) or DRV (2mm × minimum order quantities may apply. 2mm SON-6) Package Options The TPS780 series are designed to be compatible with the TI MSP430 and other similar products. The enable pin is compatible with standard CMOS logic. • TI MSP430 Attach Applications This LDO is stable with any output capacitor greater • Power Rails with Programming Mode than 1.0 µF. Therefore, implementations of this device • Dual Voltage Levels for Power-Saving Mode require minimal board space because of miniaturized • Wireless Handsets, Smartphones, PDAs, MP3 packaging and a potentially small output capacitor. Players, and Other Battery-Operated Handheld The TPS780 series IQ (500nA) also come with Products thermal shutdown and current limit to protect the device during fault conditions. All packages have an operating temperature range of TJ = –40°C to +125 °C. For more cost-sensitive applications The TPS780 family of low-dropout (LDO) regulators requiring a dual-level voltage option and only on par offer the benefits of ultralow power (IQ = 500nA), IQ, consider the TPS781 series, with an IQ of 1.0µA miniaturized packaging (2 ×2 SON-6), and selectable and dynamic voltage scaling. dual-level output voltage levels. An adjustable version is also available, but does not have the capability to shift voltage levels. 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.
