TC1313  
500 mA Synchronous Buck Regulator,  
+ 300 mA LDO  
Features  
Description  
• Dual-Output Regulator (500 mA Buck Regulator  
and 300 mA Low-Dropout Regulator (LDO))  
The TC1313 device combines a 500 mA synchronous  
buck regulator and 300 mA Low-Dropout Regulator  
(LDO) to provide a highly integrated solution for  
devices that require multiple supply voltages. The  
unique combination of an integrated buck switching  
regulator and low-dropout linear regulator provides the  
lowest system cost for dual-output voltage applications  
that require one lower processor core voltage and one  
higher bias voltage.  
• Total Device Quiescent Current = 57 µA (Typical)  
• Independent Shutdown for Buck and LDO  
Outputs  
• Both Outputs Internally Compensated  
• Synchronous Buck Regulator:  
- Over 90% Typical Efficiency  
- 2.0 MHz Fixed-Frequency PWM  
(Heavy Load)  
The 500 mA synchronous buck regulator switches at a  
fixed frequency of 2.0 MHz when the load is heavy,  
providing a low-noise, small-size solution. When the  
load on the buck output is reduced to light levels, it  
changes operation to a Pulse Frequency Modulation  
(PFM) mode to minimize quiescent current draw from  
the battery. No intervention is necessary for smooth  
transition from one mode to another.  
- Low Output Noise  
- Automatic PWM-to-PFM mode transition  
- Adjustable (0.8V to 4.5V) and Standard  
Fixed-Output Voltages (0.8V, 1.2V, 1.5V,  
1.8V, 2.5V, 3.3V)  
• Low-Dropout Regulator:  
The LDO provides a 300 mA auxiliary output that  
requires a single 1 µF ceramic output capacitor,  
minimizing board area and cost. The typical dropout  
voltage for the LDO output is 137 mV for a 200 mA  
load.  
- Low-Dropout Voltage = 137 mV Typical @  
200 mA  
- Standard Fixed-Output Voltages  
(1.5V, 1.8V, 2.5V, 3.3V)  
• Small 10-pin 3x3 DFN or MSOP Package Options  
• Operating Junction Temperature Range:  
- -40°C to +125°C  
The TC1313 device is available in either the 10-pin DFN  
or MSOP package.  
Additional protection features include: UVLO,  
overtemperature and overcurrent protection on both  
outputs.  
• Undervoltage Lockout (UVLO)  
• Output Short Circuit Protection  
• Overtemperature Protection  
For a complete listing of TC1313 standard parts,  
consult your Microchip representative.
