LDO регуляторы напряжения TPS780330200DDCT

Фиксированный стабилизатор с малым падением напряжения , 2.5В-5.5В (Vin), 250мВ, 3.3В/150мА, SOT-5

The TPS780330200DDCT is a 150mA low dropout regulator in 5 pin SOT package. This LDO has ultra low power, IQ 500nA with pin-selectable, dual level output voltage levels with the VSET pin. The ultralow power and dynamic voltage scaling (DVS) capability which provides dual-level output voltages let designers customize power consumption for specific applications. Designers can now shift to a lower voltage level in a battery-powered design when the microprocessor is in sleep mode, further reducing overall system power consumption. The two voltage levels are preset at the factory and is stored using EPROM. This IC is designed to be compatible with the TI MSP430 and other similar products. The enable pin is compatible with standard CMOS logic and also come with thermal shutdown and current limit to protect the device during fault conditions. It is used in power rails with programming mode, dual voltage levels for power saving mode and wireless handsets.

• Input voltage range from 2.5V to 5.5V
• Low dropout of 200mV at 150mA
• 3% accuracy over load, line and temperature
• VSET pin toggles output voltage between two factory programmed voltage levels
• Stable with a 1µF ceramic capacitor
• Thermal shutdown and overcurrent protection
• CMOS logic level compatible enable pin
