TC1301B
Description
The TC1301A/B combines two Low Dropout (LDO) regulators and a microcontroller RESET function into a single 8-pin MSOP or DFN package. Both regulator outputs feature low dropout voltage, 104 mV @ 300 mA for VOUT1, 150 mV @ 150 mA for VOUT2, low quiescent current consumption, 58 µA each and a typical regulation accuracy of 0.5%.
Key Features
- Dual Output LDO with Microcontroller Reset Monitor Functionality: - VOUT1 = 1.5V to 3.3V @ 300 mA - VOUT2 = 1.5V to 3.3V @ 150 mA - VRESET = 2.20V to 3.20V
- Output Voltage and RESET Threshold Voltage Options Available (See Table 8-1)
- Low Dropout Voltage: - VOUT1 = 104 mV @ 300 mA (typical) - VOUT2 = 150 mV @ 150 mA, (typical)
- Low Supply Current: 116 µA (typical), TC1301A/B with both output voltages available
- Reference Bypass Input for Low-Noise Operation
- Both Output Voltages Stable with a Minimum of 1 µF Ceramic Output Capacitor
- Separate Input for RESET Detect Voltage (TC1301A)
- Separate VOUT1 and VOUT2 SHDN pins (TC1301B)
- RESET Output Duration: 300 ms (typical)
- Power-Saving Shutdown Mode of Operation
