11.5. TL431
11.5.1. General
Description
The TL431/TL431Aare three-terminal adjustable regulator series with a guaranteed thermal stability
over applicable temperature ranges. The output voltage may be set to any value between Vref
(approximately 2.5 volts) and 36 volts with two external resistors These devices have a typical dynamic
output impedance of 0.2W Active output circuitry provides a very sharp turn-on characteristic, making
these devices excel lent replacement for zener diodes in many applications.

11.6. 24C32
11.6.1. General
Description
The Microchip Technology Inc. 24C32 is a 4K x 8 (32K bit) Serial Electrically Erasable PROM. This
device has been developed for advanced, low power applications such as personal communications or
data acquisition. The 24C32 features an input cache for fast write loads with a capacity of eight 8-byte
pages, or 64 bytes. It also features a fixed 4K-bit block of ultra-high endurance memory for data that
changes frequently. The 24C32 is capable of both random and sequential reads up to the 32K
boundary. Functional address lines allow up to 8 - 24C32 devices on the same bus, for up to 256K bits
address space. Advanced CMOS technology makes this device ideal for low-power non-volatile code
and data applications.
11.6.2. Features
• Voltage operating range: 4.5V to 5.5V
- Peak write current 3 mA at 5.5V
- Maximum read current 150μA at 5.5V
- Standby current 1μA typical
• Industry standard two-wire bus protocol, I
2
C™ compatible
-Including 100 kHz and 400 kHz modes
• Self-timed write cycle (including auto-erase)
• Power on/off data protection circuitry
• Endurance:
