PFM Step-Up DC/DC Regulators  
GENERAL DESCRIPTION  
FEATURES  
■ Space-Saving 5-Pin SOT-23A Package  
■ Guaranteed 0.9V Start-Up  
■ PFM (100 KHz Max Operating Frequency)  
■ 40 µA Maximum Supply Current (VOUT = 3V @ 30 mA)  
■ 0.5 µA Shutdown Mode (TC125)  
■ Voltage Sense Input (TC126)  
■ Requires Only Three External Components  
■ 80 mA Maximum Output Current  
The TC125/6 step-up (Boost) switching regulators fur-  
nish output currents to a maximum of 80 mA (VIN = 2V,  
VOUT = 3V) with typical efficiencies above 80%. These  
devices employ pulse frequency modulation (PFM) for mini-  
mum supply current at low loads. They are ideal for battery-  
operated applications powered from one or more cells.  
Maximum supply current is less than 70 µA at full output  
load, and less than 5 µA in standby (VOUT = 3V). Both  
devicesrequireonlyanexternalinductor,diode,andcapaci-  
tor to implement a complete DC/DC regulator.  
The TC126 has separate output voltage sensing and  
chip power inputs for greater application flexibility. The  
TC125combinestheoutputvoltagesensingandchippower  
inputs onto a single package pin, but adds a power-saving  
shutdown mode that suspends regulator operation and  
reduces supply current to less than 0.5 µA when the  
shutdown control input (SHDN) is low.  
TYPICAL APPLICATIONS  
■ Palmtops/PDAs  
■ Battery-Powered Systems  
■ Cameras  
■ Portable Communicators  
ORDERING INFORMATION  
Housed in tiny 5-Pin SOT-23A packages, the  
TC125/6 occupy minimum board space, and use tiny  
external components. The TC125 accepts input voltages  
from 2.0V to 10.0V. The TC126 accepts input voltages from  
2.2V to 10V. Both the TC125 and TC126 have a guaranteed  
start-up voltage of 0.9V at light load.
