ISL9000AIRBJZ-T

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

The ISL9000AIRBJZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides two fixed positive output voltages of 1.5V and 2.8V, each capable of sourcing up to 300mA. The device operates with an input voltage range from 2.3V to 6.5V and features a maximum dropout voltage of 0.4V at full load. It incorporates individual power-on-reset functions for each output channel and includes protection mechanisms such as overcurrent, thermal shutdown, and undervoltage lockout. The component is housed in a 10-lead DFN package measuring 3x3mm.

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

Verify current availability status as this component may be discontinued or subject to end-of-life notices. Confirm exact pinout compatibility and thermal requirements during integration. Ensure that the fixed output voltages align with target system specifications since the device does not support external adjustment. Check for alternative packages if lead-free compliance or specific moisture sensitivity levels are required for the manufacturing process.

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

Select this component when a compact dual-output solution is needed for low-noise applications. The fixed 1.5V and 2.8V outputs eliminate the need for external resistors, simplifying board layout. Consider the 300mA current limit per channel against peak load demands. The small 3x3mm footprint makes it suitable for space-constrained designs compared to larger regulator packages.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the ISL9000 series of high-performance dual LDOs designed for low standby current and high power supply rejection ratio (PSRR). The series is characterized by stability with ceramic capacitors ranging from 1µF to 10µF. It is commonly used in conjunction with Renesas microcontrollers and other mixed-signal ICs where clean power delivery is critical.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for direct replacements within the ISL9000A family with different output voltage combinations. Verify if newer Renesas PMICs offer similar dual-output capabilities with updated packaging or enhanced efficiency metrics.
