Frequently Asked Questions
What is the output voltage range of the TLV62565DBVT?
The TLV62565DBVT provides an adjustable output voltage from 0.6V to 5.225V, set by an external resistor divider connected to the feedback pin. This flexibility makes it suitable for powering a wide variety of processor cores, memory, and peripheral ICs from a single regulator.
What input voltage range does the TLV62565DBVT support?
The TLV62565DBVT accepts an input voltage from 2.7V to 5.5V, with a nominal operating point around 3.6V. This range covers single-cell lithium-ion batteries (2.7V–4.2V) as well as regulated 3.3V and 5V system rails, making it versatile for both battery-powered and wall-powered designs.
How does the PFM control mode benefit light-load efficiency?
In addition to PWM (Pulse Width Modulation), the TLV62565DBVT automatically enters PFM (Pulse Frequency Modulation) mode at light loads. PFM reduces switching losses by decreasing the switching frequency when output current demand is low, significantly improving efficiency in standby or sleep states—critical for extending battery life in IoT and portable devices.
What package does the TLV62565DBVT come in and what are its dimensions?
The TLV62565DBVT is housed in a SOT-23 5-pin (JEDEC R-PDSO-G5) package, one of the smallest industry-standard packages available. Its tiny footprint makes it ideal for space-constrained PCB layouts in wearables, hearing aids, and compact IoT modules where board area is at a premium.
Is the TLV62565DBVT RoHS compliant and what alternatives exist?
Yes, the TLV62565DBVT is lead-free (Pb-free) and RoHS compliant, suitable for environmentally regulated markets. Close alternatives from Texas Instruments include the TLV62568 (higher current) and TLV62130 (up to 3A). When substituting, verify input/output voltage range, maximum output current, and package footprint compatibility.
