LP4951C LP4950C and micropower regulators with very low quiescent current (75μA typical) and very low dropout voltage of 380mV at light load of 100mA (typical difference of less than 40mV). They are ideal for using battery-powered systems. In addition, the LP4950C/LP4951C increase in quiescent current is only possible at dropouts, extending battery life.
The popular 3-pin TO-92 package in LP4950C is compatible with older 5V regulator pins. The 8-lead LP4951C is a plastic surface mount package and provides additional system functionality.
One such feature is an error flag warning of low output voltage, often due to a drop in battery input and output. It can be used for power-on reset. The second feature is logic-compatible shutdown inputs, allowing the regulator to be turned on and off. In addition, parts can be programmed for a 5V output pin or an external resistor from 1.24V to 29V constraints.
All contributions to a well-designed LP4950C/LP4951C minimum error budget. This includes tight initial tolerances (0.5% typical). , very good load and row gauge" (0.05% typical. ) and a very low output voltage temperature coefficient, making the part a low-power voltage reference.
