The TLV431A/D series of low voltage precision adjustable shunt regulators are programmable over a wide voltage range of 1.24V to 16V. The TLV431A series features a guaranteed reference accuracy of ±1.0% at 25°C and ±2.0% over the entire industrial temperature range of −40°C to 85°C. For TLV431B series, the accuracy is even higher, it’s ±0.5% and ±1.0% respectively. These devices exhibit a sharp low current turn−on characteristic with a low dynamic impedance of 0.20 Ω over an operating current range of 100μA to 20mA. This combination of features makes this series an excellent replacement for zener diodes in numerous applications circuits that require a precise reference voltage. When combined with an optocoupler, the TLV431A/B can be used as an error amplifier for controlling the feedback loop in isolated low output voltage (3.0 V to 3.3 V) switching power supplies. These devices are available in economical TO−92−3 and micro size TSOP−5 and SOT−23−3 packages.

The NCP1402 is a 200mA, PFM step-up micropower switching regulator from Semiconductor Components Industries.

MC14099B is an 8-bit addressable latch. Data is entered in serial form when the appropriate latch is addressed (via address pins A0, A1, A2) and write disable is in the low state. For the MC14099B the input is a unidirectional write only port. The data is presented in parallel at the output of the eight latches independently of the state of Write Disable, Write/Read or Chip Enable. A Master Reset capability is available on both parts.
