Microchip Technology Inc. introduces the TC1303/TC1304 and TC1313 series of power management integrated circuits that combine a synchronous buck switching regulator, low dropout regulator (LDO) and power-good function into single-chip components. These five devices offer low-power and low-cost advantages for a variety of battery-operated and dual-output-voltage systems. The power management ICs include: TC1303A, &#151 500 mA synchronous buck regulator and 300 mA LDO with a power-good function on the DC/DC converter output; TC1303B &#151 a 500 mA synchronous buck regulator and 300 mA LDO with a power-good function on the LDO output; TC1303C &#151 500 mA synchronous buck regulator and 300 mA LDO with a power-good function on the LDO and DC/DC converter outputs; TC1304 &#151 500 mA synchronous buck regulator and 300 mA LDO with power sequencing; TC1313 &#151 500 mA synchronous buck regulator and 300 mA LDO.
