LR432ATLT1G
Description
The LR432ATLT1G is a three-terminal adjustable regulator
with a guaranteed thermal stability over applicable temperature
ranges.The output voltage may be set to any value between VREF
(approximately 1.24V) and 18V with two external resistors. It
provides very wide applications,including shunt regulator,series
regulator,switching regulator,voltage reference and others.

Tape & Reel and Packaging Specifications
Embossed Tape and Reel is used to facilitate automatic pick and place equipment feed requirements. The tape is used as the
shipping container for various products and requires a minimum of handling. The antistatic/conductive tape provides a secure
cavity for the product when sealed with the “peel–back” cover tape.
• Two Reel Sizes Available (7"and 13",)
• SOT–23, SC–70/SOT–323,
• Used for Automatic Pick and Place Feed Systems
SC–89, SC–88/SOT–363, SC–88A/SOT–353,
• Minimizes Product Handling
SOD–323, SOD-523 in 8 mm Tape
• EIA 481, –1, –2
Use the standard device title and add the required suffix as listed in the option table below (Table 1). Note that the individual
reels have a finite number of devices depending on the type of product contained in the tape. Also note the minimum lot size is
one full reel for each line item, and orders are required to be in increments of the single reel quantity.

Metric dimensions govern - English are in parentheses for reference only.
NOTE 1: A 0 , B 0 , and K 0 are determined by component size. The clearance between the components and the cavity must be within
.05 mm min. to.50 mm max.,
NOTE 2: the component cannot rotate more than 10 o within the determined cavity.
NOTE 3: If B1 exceeds 4.2 mm (.165”) for 8 mm embossed tape, the tape may not feed through all tape feeders.
