Product details

2 µA quiescent current — the always-on enabler

The TCR2LF32,LM(CT draws a typical quiescent current of 2 µA. For a 200 mA LDO, that is the difference between a battery that lasts the product life and one that needs quarterly replacement. The fixed 3.2 V output and enable pin let the system power-rail sequence without an external supervisor — pull the enable low and the regulator drops to near-zero draw.

Dropout and headroom at the load point

Maximum dropout is 0.3 V at 150 mA. That means with a 5.5 V max input, a 3.2 V rail stays regulated as long as the input stays above 3.5 V at full load. The 200 mA continuous output is the nominal ceiling — the over-current protection clips the output if the load tries to pull more, so the downstream circuitry sees a hard current limit rather than a voltage sag.

Sourcing and package form

Frequently asked questions

Can TCR2LF32,LM(CT be used with a 5V input to output 3.2V at 200mA?

Yes. The maximum input voltage is 5.5 V, and the dropout is 0.3 V at 150 mA. At 200 mA the dropout will be slightly higher but still below 0.5 V, so 5 V in gives more than enough headroom for a clean 3.2 V output.

Is TCR2LF32,LM(CT compatible with 3.3V input?

3.3 V in to 3.2 V out leaves only 0.1 V headroom. The dropout at 150 mA is 0.3 V max, so at any load above roughly 50 mA the regulator will drop out of regulation. A 3.3 V rail is not a suitable input for this part — use a 3.3 V fixed-output variant instead.
