MCP1826/MCP1826S 1000 mA, Low-Voltage, Low Quiescent Current LDO Regulator Features Description 1000 mA Output Current Capability The MCP1826/MCP1826S is a 1000 mA Low Dropout (LDO) linear regulator that provides high-current and Input Operating Voltage Range: 2.3V to 6.0V low-output voltages. The MCP1826 comes in a fixed or Adjustable Output Voltage Range: 0.8V to 5.0V adjustable output voltage version, with an output (MCP1826 only) voltage range of 0.8V to 5.0V. The 1000 mA output cur- Standard Fixed Output Voltages: rent capability, combined with the low-output voltage - 0.8V, 1.2V, 1.8V, 2.5V, 3.0V, 3.3V, 5.0V capability, make the MCP1826 a good choice for new Other Fixed Output Voltage Options Available sub-1.8V output voltage LDO applications that have Upon Request high current demands. The MCP1826S is a 3-pin fixed voltage version. Low Dropout Voltage: 250 mV Typical at 1000 mA Typical Output Voltage Tolerance: 0.5% The MCP1826/MCP1826S is stable using ceramic output capacitors that inherently provide lower output Stable with 1.0 F Ceramic Output Capacitor noise and reduce the size and cost of the entire Fast Response to Load Transients regulator solution. Only 1 F of output capacitance is Low Supply Current: 120 A (typ) needed to stabilize the LDO. Low Shutdown Supply Current: 0.1 A (typ) Using CMOS construction, the quiescent current (MCP1826 only) consumed by the MCP1826/MCP1826S is typically Fixed Delay on Power Good Output less than 120 A over the entire input voltage range, (MCP1826 only) making it attractive for portable computing applications Short Circuit Current Limiting and that demand high-output current. The MCP1826 Overtemperature Protection versions have a Shutdown (SHDN) pin. When shut TO-263-5 (DDPAK-5), TO-220-5, SOT-223-5 down, the quiescent current is reduced to less than Package Options (MCP1826) 0.1 A. TO-263-3 (DDPAK-3), TO-220-3, SOT-223-3 On the MCP1826 fixed output versions the Package Options (MCP1826S) scaled-down output voltage is internally monitored and Pass Automotive AEC-Q100 Reliability Testing a power good (PWRGD) output is provided when the output is within 92% of regulation (typical). The PWRGD delay is internally fixed at 200 s (typical). Applications: The overtemperature and short circuit current-limiting High-Speed Driver Chipset Power provide additional protection for the LDO during system Networking Backplane Cards Fault conditions.
