[Omnirel]

DESCRIPTION
The OM955X series of Switching Regulators are designed for pin compatibility with standard 3- Pin linear Regulators. They are well suited for on-board, non- isolated power applications where efficient point- of- load regulation is needed. The package is designed using Chip- on – Board technology to reduce cost and maintain power density. These units will typically not require any additional components in your application due to capacitance provided internal to the package.

FEATURES
• High Efficiency
• Internal Short Circuit Protection
• Small Footprint
• High Power Density- 60W/in.3

APPLICATIONS
• High Power 5V to 3.3V Regulation
• Low Voltage Battery regulation
• Embedded Processor Power
• General Purpose Low Voltage Logic Supply
• FPGA Power

Description : 8V/1A, 5V/250mA Dual Regulator with Independent Output Enables and NoCap™

Description
The CS8371 is a 8V/5V dual output linear Regulator. The 8V ±5% output sources 1A, while the 5V ±5% output sources 250mA. Each output is controlled by its own ENABLE lead. Setting the ENABLE input high turns on the associated Regulator output. Holding both ENABLE inputs low puts the IC into sleep mode where current consumption is less than 10µA.

Features
■ Two Regulated Outputs 8V ±5%, 1A 5V ±5%, 250mA
■ Independent ENABLE for each Output
■ Separate Sense Feedback Lead for 8V Output
■ <10µA Sleep Mode Current
■ Fault Protection Overvoltage Shutdown +45V Peak Transient Voltage Short Circuit Thermal Shutdown
■ CMOS Compatible, Low-Current ENABLE Inputs
