●Description
The BD3540NUV, BD3541NUV low-voltage output linear 1ch series chipset regulator IC operates from a very low input
supply, and offers ideal performance in low input voltage to low output voltage applications. It incorporates a built-in
N-MOSFET power transistor to minimize the input-to-output voltage differential to the ON resistance (R
ON
=200mΩ½
400mΩ) level. By lowering the dropout voltage in this way, the regulator realizes high current output (Iomax=0.5A½1.0A)
with reduced conversion loss, and thereby obviates the switching regulator and its power transistor, choke coil, and rectifier
diode. Thus, the BD3540NUV, BD3541NUV are designed to enable significant package profile downsizing and cost
reduction. An external resistor allows the entire range of output voltage configurations between 0.65 and 2.7V, while the
NRCS (soft start) function enables a controlled output voltage ramp-up, which can be programmed to whatever power
supply sequence is required.
●Features
1) High-precision voltage regulator(0.65V±1%)
2) Built-in VCC undervoltage lockout circuit
3) NRCS (soft start) function reduces the magnitude of in-rush current
4) Internal Nch MOSFET driver offers low ON resistance
5) Built-in current limit circuit
6) Built-in thermal shutdown (TSD) circuit
7) Variable output
8) Small package VSON010V3030 : 3.0×3.0×1.0(mm)
9) Tracking function
●Applications
Notebook computers, Desktop computers, LCD-TV, DVD, Digital appliances
●Line-up
It is available to select power supply voltage and maximum output voltage.
