LM385BLP-2-5

The LMx85-2.5 and LM385B are micropower, two-terminal, bandgap voltage reference devices. They operate with a current range from 20 μA to 20 mA, featuring extremely low dynamic impedance and good temperature stability. On-chip trimming can provide a smaller voltage tolerance range. The bandgap references of these devices are characterized by low noise and long-term stability. This design makes these devices highly immune to capacitive loads, thus being easier to use in most applications where low power consumption is a critical issue. The wide dynamic operating temperature range can meet various current supply requirements and offers excellent voltage regulation. The ultra-low power consumption of this series makes these devices very useful for micropower circuits. These voltage references can be used in the design of portable instruments, voltage regulators, or general analog circuits with a battery life close to the shelf life. The wide operating current range of these voltage references enables the replacement of old references with devices having a smaller tolerance range.
