LM385-1.2KW03ABAQ

The LM385-1.2 is a micropower two-terminal bandgap voltage reference zener diode. It operates over a current range of 10μA to 20mA, featuring very low dynamic impedance and excellent temperature stability. On-chip trimming ensures tight voltage tolerances. Since the bandgap reference uses only transistors and resistors, it exhibits low noise and long-term stability. The careful design gives the device excellent tolerance to capacitive loads, making it easy to use in most reference applications. The wide dynamic operating range allows it to deliver superior regulation performance even with large variations in supply voltage. The ultra-low power consumption of the LM385-1.2 makes it suitable for micropower circuits. This voltage reference can be used to build portable instruments, regulators, or general-purpose analog circuits with battery life approaching shelf life. The wide operating current range allows it to replace older reference sources with higher tolerance accuracy components.
