nanoSmart® Ultra-Low-Power Linear Regulator
TRIUNE PRODUCTS
Features
• Ultra-low nA operating current at light load • Best-in-class quiescent current of 20nA at Iload=0 • Best-in-class quiescent current of 100pA in disable mode • Output voltage options of 1.2V - 4.2V in 100mV steps (pro-
grammed at manufacturing) • Accurate output regulation • Over-current protection
Summary Specifications
• Low input operating voltage of 2.5V to 5.5V • Packaged in a 8pin DFN (2x2)
Description
The TS14002 linear regulator is an ultra-low-power circuit which draws low nA level quiescent current at light load, but has the capability to regulate current loads as high as 200mA.
Applications
• Portable electronics • RFID • Industrial • Medical • Energy harvesting systems • SmartCard

(2) 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.
(3) All voltage values are with respect to network ground terminal. (4) ESD testing is performed according to the respective JESD22 JEDEC standard.
