- Fixed 3.3 V regulated output from 2 V to 4.4 V input for single-cell Li-ion and alkaline battery applications
- Integrated shutdown pin allows microcontroller power management to cut supply in sleep modes for lower quiescent current
- 6-pin SOT-23 package occupies minimal board area for ultra-compact portable device designs
Applications
LTC1754ES6-3.3#TRMPBF is designed for generating a regulated 3.3 V rail in battery-operated portable electronics such as handheld instruments, wireless sensor nodes, and IoT devices powered from single-cell Li-ion (2.5 V nominal) or primary alkaline cells (2 V to 4.4 V range). Its inductor-free charge pump topology eliminates EMI concerns from switching inductors, making it well-suited for noise-sensitive RF and analog circuits requiring a clean 3.3 V supply. The shutdown function also enables power sequencing and sleep-mode control in microcontroller-managed systems to extend battery life.

Frequently Asked Questions
What input voltage range does LTC1754ES6-3.3#TRMPBF support and which battery chemistries does this span?
LTC1754ES6-3.3#TRMPBF accepts an input voltage of 2 V to 4.4 V, covering the full discharge range of single-cell Li-ion batteries (nominally 2.5 V to 4.2 V) as well as two-cell alkaline primary batteries (nominally 2.4 V to 3.2 V). This broad input range allows the device to maintain a stable 3.3 V output even as the battery discharges, maximizing useful battery life in portable sensors, handheld devices, and wireless modules.
How does the switched-capacitor topology of LTC1754ES6-3.3#TRMPBF eliminate PCB layout concerns associated with inductive switching regulators?
LTC1754ES6-3.3#TRMPBF uses a switched-capacitor charge pump architecture that requires only small fly capacitors (typically 1 µF to 10 µF) rather than power inductors, eliminating the magnetic flux emissions and layout-sensitive placement rules associated with inductive DC-DC converters. This makes it ideal for noise-sensitive RF front-ends and analog signal chains in 3.3 V portable systems where inductor-generated switching noise would degrade signal quality.
How can the shutdown pin on LTC1754ES6-3.3#TRMPBF be used to reduce system power consumption in microcontroller-managed designs?
The active-low shutdown pin on LTC1754ES6-3.3#TRMPBF allows a microcontroller GPIO to disable the charge pump regulator entirely during sleep or standby modes, reducing the 3.3 V rail current to near zero. In IoT sensor nodes that spend 99% of their duty cycle in deep sleep, toggling this pin before entering low-power mode and re-enabling the 3.3 V output only during active measurement windows can extend battery life from weeks to months in a 2 V to 4.4 V primary cell powered design.
What external components are required with LTC1754ES6-3.3#TRMPBF and how does this simplify the power supply BOM?
LTC1754ES6-3.3#TRMPBF requires only 2 to 3 small ceramic capacitors (typically 1 µF to 10 µF each) for the flying capacitor and output filter, with no inductors, transformers, or feedback resistors needed. This reduces the BOM to fewer than 5 components for a complete 3.3 V regulated supply in a 6-pin SOT-23 footprint measuring approximately 2.9 mm × 1.6 mm, making it one of the simplest solutions for generating a 3.3 V rail from a single-cell battery source.
