AS1364-BTDT-15-1K

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AS1364-BTDT-15-1K is a linear low-dropout (LDO) voltage regulator manufactured by ams OSRAM. It provides a fixed positive output of 1.5V with a maximum continuous output current of 400mA. The device operates within an input voltage range up to 3.6V and features a typical dropout voltage of 80mV at full load. Key electrical characteristics include a quiescent current of 20µA and a power supply rejection ratio (PSRR) of 50dB at 10kHz. Integrated protection mechanisms include overcurrent limiting, thermal shutdown, and under-voltage lockout (UVLO). The component is housed in a compact 6-TDFN (2x2mm) surface-mount package and supports operation across an extended temperature range from -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix '1K' against official manufacturer documentation to confirm if it denotes a specific tape-and-reel quantity or packaging variant, as standard datasheets may only list the base part number. Confirm availability status as components in this series may be subject to discontinuation notices. Ensure compatibility with your PCB footprint for the 6-TDFN package before finalizing procurement orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 1.5V output is required with high efficiency at moderate loads. The low dropout voltage allows operation from single-cell lithium batteries. Consider the 6-TDFN package size for space-constrained designs. Verify that the 400mA output current meets the peak demand of the load circuit while maintaining thermal performance within the specified operating temperature range.
