... Output Voltage Sense Input (ADJ) The output voltage adjust pin (ADJ) for the adjustable output voltage version of the MCP1726 allows the user to set the output voltage of the LDO by using two external resistors. The adjust pin voltage is 0.41V (typical). ...
Page 14
... If the output voltage falls below 0.7V due to an overload condition (usually represents a shorted load condition), the output current is limited to 1.7A (typical). If the over- load condition is a soft overload, the MCP1726 will sup- ply higher load currents 3A. The MCP1726 should not be operated in this condition continuously as it may result in failure of the device ...

... See the Electrical Characteristics table for maximum dropout voltage specifications. The MCP1726 LDO operates across an input voltage range of 2.3V to 6.0V and incorporates input Undervolt- age Lockout (UVLO) circuitry that keeps the LDO output voltage off until the input voltage reaches a minimum of 2 ...
Page 17
... Overtemperature Protection The MCP1726 LDO has temperature-sensing circuitry to prevent the junction temperature from exceeding approximately 150 C. If the LDO junction temperature ° does reach 150 C, the LDO output will be turned off ° until the junction temperature cools to approximately 140 C, at which point the LDO output will automatically ° ...

... C IN(MAX µ Current flowing in the V VIN The total power dissipated within the MCP1726 is the sum of the power dissipated in the LDO pass device and the P(I GND PWRGD tion, the typical I Operating at a maximum of 3.63V results in a power dissipation of 0.51 milli-Watts. For most applications, this is small compared to the LDO pass device power dissipation and can be neglected ...
