First Claim
1. A trainable transceiver unit comprising:
- a transceiver circuit configured to reproduce and transmit control signals for operating a plurality of remote electronic devices;
a user input device configured to accept user input;
a battery; and
a voltage regulator circuit comprising;
a DC-DC converter configured to step up the battery voltage level;
a low leakage switch configured to couple the battery and the DC-DC converter; and
a temperature-sensitive current source configured to increase the base drive current from the battery to the low leakage switch when a current gain of the low-leakage switch decreases from a decrease in temperature;
wherein the battery is configured to power the transceiver circuit, the user input device, and the voltage regulator circuit.
