General Description

: The TC125/126 step-up (Boost) switching regulators furnish 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 minimum supply current at low loads.

They are ideal for battery-operated applications powered from one or more cells.

Key Features

Assured Start-up at 0.9V.
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.
Small Package: 5-Pin SOT-23.
