Voltage Regulators - DC DC Switching Regulators datasheet and documents for MAX889SESA+T

MAX889SESA+T

Voltage Regulators - DC DC Switching Regulators Overview

The MAX889SESA+T is a high-frequency, regulated inverting charge pump switch regulator manufactured by Analog Devices Inc./Maxim Integrated. It provides an adjustable negative output voltage ranging from -2.5V to -5.5V with a maximum output current of 200mA. The device operates from an input voltage range of 2.7V to 5.5V and utilizes a fixed switching frequency of 1MHz. It is housed in an 8-SOIC surface-mount package and supports an operating temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Inverting topology converts positive input voltages to regulated negative outputs
Integrated regulation maintains stable output voltage under varying load conditions
High switching frequency enables the use of small external passive components

Voltage Regulators - DC DC Switching Regulators Applications

RS-232 transceiver power supply generation
LCD bias voltage generation
Op-amp dual supply creation
Negative rail provision for mixed-signal circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging rather than tube packaging when sourcing. Confirm the manufacturer designation matches Analog Devices Inc. or Maxim Integrated as per current corporate structure. Ensure RoHS compliance status aligns with project requirements. Cross-reference the specific lot date code against component authenticity databases to prevent counterfeit infiltration during procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution for generating negative voltage rails from a single positive source is required. The 1MHz switching frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Verify that the 200mA output current capability meets the target circuit's peak demand. Consider thermal dissipation within the 8-SOIC package if operating near maximum input-output differentials.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX889 family of high-frequency charge pumps designed for portable applications where space is limited. It serves as a specialized PMIC solution for creating inverted supplies without requiring complex transformer-based designs. The series is commonly integrated into communication interfaces and sensor systems requiring bipolar power supplies.
