2/25/2004 - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced a Low Dropout Regulator (LDO), stable with ceramic capacitors, that operates at a very low supply current. Attachable to practically any microcontroller, this device is a low-cost, low-power LDO ideal for virtually any portable or battery-powered application.
Microchip’s MCP1700 LDO can deliver up to 250 milliamps of current while consuming only 1.6 microamps of quiescent current (typical). This device maximizes battery life with a dropout voltage of 178 millivolts at 250 milliamps; increases performance with an output voltage accuracy of +/-0.4 percent and exceeds in dynamic behavior with better line (+/- .75 percent V) and load (+/-1.0 percent V) regulation.
The MCP1700 enables the use of low-cost ceramic capacitors on the input and output, which reduces the system cost. This LDO is stable with 1-microfarad (uF) output capacitor; meanwhile, its overcurrent limit and overtemperature shutdown provides a robust solution for any application.
“This device offers the use of low cost ceramic capacitors, low supply current, tighter output-voltage tolerance, lower dropout at rated current and tighter specifications across the range. This gives designers an LDO that helps reduce costs and increase battery life, and allows the application to operate at a lower input voltage,” said Keith Pazul, senior marketing manager for Microchip’s Analog and Interface Products Division.
Attachable to virtually any microcontroller, including Microchip’s PIC® microcontroller family, this device is available in three-pin, SOT 23, SOT 89 and TO 92 packages. Pricing in 10,000-unit quantities is $0.39 USD each. Samples and volume production are available now.
