TC1301A/B  
Dual LDO with Microcontroller RESET Function  
Features  
Description  
• Dual Output LDO with Microcontroller Reset  
Monitor Functionality:  
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  
- VOUT1 = 1.5V to 3.3V @ 300 mA  
- VOUT2 = 1.5V to 3.3V @ 150 mA  
- VRESET = 2.20V to 3.20V  
@ 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%. Several fixed-  
output voltage and detector voltage combinations are  
available. A reference bypass pin is available to further  
reduce output noise and improve the power supply  
rejection ratio of both LDOs.  
• 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  
The TC1301A/B is stable over all line and load  
conditions with a minimum of 1 µF of ceramic output  
capacitance, and utilizes a unique compensation  
scheme to provide fast dynamic response to sudden  
line voltage and load current changes.  
• 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  
For the TC1301A, the microcontroller RESET function  
operates independently of both VOUT1 and VOUT2. The  
input to the RESET function is connected to the VDET  
pin.The SHDN2 pin is used to control the output of  
• Separate Input for RESET Detect Voltage  
(TC1301A)  
• Separate VOUT1 and VOUT2 SHDN pins  
(TC1301B)  
V
OUT2 only. VOUT1 will power-up and down with VIN.  
In the case of the TC1301B, the detect voltage input of  
the RESET function is connected internally to VOUT1  
• RESET Output Duration: 300 ms. Typical  
• Power-Saving Shutdown Mode of Operation  
• Wake-up from SHDN: 5.3 µs. Typical  
• Small 8-pin DFN and MSOP Package Options  
• Operating Junction Temperature Range:  
- -40°C to +125°C  
.
Both VOUT1 and VOUT2 have independent shutdown  
capability.  
Additional features include an overcurrent limit and  
overtemperature protection that, when combined,  
provide a robust design for all load fault conditions.  
• Overtemperature and Overcurrent Protection  
Applications  
Package Types  
• Cellular/GSM/PHS Phones  
• Battery-Operated Systems  
• Hand-Held Medical Instruments  
• Portable Computers/PDAs  
• Linear Post-Regulators for SMPS  
• Pagers
