Status: In Production
The TC1223 and TC1224 are high accuracy (typically ±0.5%) CMOS upgrade for older (bipolar) low dropout regulators such as the LP2980. Designed specifically for battery-operated systems, the devices CMOS constructio neliminates wasted ground current, significantly extending battery life. Total supply current is typically 50 µA at full load ( 20 to 60 times lower than in bipolar regulators!). Key features for the TC1223 and TC1224 include ultra low-noise operation; very low dropout voltage (typically 85 mV and 180 mV,respectively, at full load) and fast response to step changes in load. Supply current is reduced to 0.5 µA (max) and VOUT falls to zero when the shutdown input is low. The devices also incorporate both over-temperature and over-current protection. The TC1223 and TC1224 are stable with an output capacitor of only 1 µF and have a maximum output current of 50 mA and 100 mA, respectively. For higher output versions, please see the TC1107, TC1108, and TC1173 (IOUT = 300 mA) data sheets.
This Blank PCB allows the system designer to quickly evaluate the operation of Microchip Technology’s Voltage Supervisors and Voltage Detectors in the SOT-23-5 (5-pin) and SOT-23-6 (6-pin) packages. This PCB supports many Microchip device families, including the Nonvolitile Digital Potentiometer and PIC10F2xx devices.
