ISL9000AIRBCZ-T

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

The ISL9000AIRBCZ-T is a dual-output low dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It features two fixed output channels providing 1.5 V and 1.8 V, respectively. The device supports a maximum output current of 300 mA per channel with an input voltage range from 2.3 V to 6.5 V. Key electrical specifications include a typical quiescent current of 32 µA, power supply rejection ratio (PSRR) ranging from 90 dB at 1 kHz to 50 dB at 100 kHz, and a maximum dropout voltage of 0.4 V at 300 mA load. The unit offers high accuracy with 0.8% voltage regulation tolerance and 0.1% load regulation. Integrated protection mechanisms include overcurrent, thermal overload, and undervoltage lockout (UVLO).

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

Verify component authenticity through authorized distributors due to potential counterfeit risks in the market. Confirm that the specific suffix 'BC' corresponds to the required 1.5 V/1.8 V output configuration, as other suffixes may indicate different voltage combinations. Ensure compliance with RoHS directives if environmental regulations apply to your manufacturing process. Check for end-of-life notices or obsolescence warnings, as availability may be limited for discontinued series components.

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

Select this component when dual isolated rails are necessary without external synchronization complexity. The fixed 1.5 V and 1.8 V outputs eliminate the need for external feedback resistors, simplifying board layout. Consider the 10-DFN package size constraints and thermal dissipation requirements for the intended application environment. Verify that the input voltage never drops below the minimum threshold of 2.3 V during operation to maintain regulation.

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

This part belongs to the ISL9000A family of low-noise, high-PSRR LDO regulators designed for portable applications. The family typically includes single and dual-output variants with various fixed voltage options. The 'AIR' designation indicates automotive-grade reliability standards, while 'BCZ' specifies the dual-output 1.5 V/1.8 V configuration in a 10-lead DFN package. This series emphasizes low power consumption and high noise immunity for sensitive analog circuits.

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

Direct substitutes may include other dual-output LDOs from Renesas such as the ISL9000AIRBBZ-T (1.5V/1.5V) or ISL9000AIRNNZ-T (3.3V/3.3V), provided the voltage requirements align. Cross-manufacturer replacements require matching pinout compatibility, current capabilities, and package dimensions. Always verify that alternative parts meet the same PSRR and quiescent current specifications to ensure system performance parity.
