LT1054CP

Voltage Regulators - DC DC Switching Regulators Overview

The LT1054CP is a monolithic, bipolar switched-capacitor voltage converter and regulator manufactured by Texas Instruments. It operates within an input voltage range of 3.5 V to 15 V and provides a fixed -5 V output with a maximum current capability of 100 mA. The device features a switching frequency of 25 kHz and a typical static current of 100 uA. Designed for through-hole installation, it utilizes a PDIP-8 package. The component supports boost and buck topologies and functions reliably across an operating temperature range from 0°C to +70°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific manufacturer designation on the datasheet, as the LT1054 family originated with Linear Technology before acquisition by Analog Devices. Confirm that the TI-sourced LT1054CP matches the required pinout and electrical specifications for your design. Ensure the PDIP-8 package variant aligns with your PCB footprint requirements. Cross-reference the revision history to confirm compatibility with existing system constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when inductor-free voltage inversion is required for low-current applications. The fixed -5 V output suits standard analog signal processing needs. Consider the 100 mA limit for load requirements. The through-hole PDIP-8 package is suitable for prototyping or high-reliability manual assembly environments where surface mount options are not preferred.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1054 belongs to a family of switched-capacitor regulators known for replacing bulky inductive converters in low-power designs. Originally developed by Linear Technology, the product line was integrated into Texas Instruments' portfolio following corporate acquisitions. This specific part represents the commercial grade version in a through-hole package, maintaining the legacy performance characteristics of the original LT1054 series.
